Diisopropylethylamine → 1-[Bis(4-chlorophenyl)methyl]azetidin-3-ol

Participants

Reaction Steps

The reaction mixture of 22.30 g (70.5 mmol) of 1-[bromo(4-chlorophenyl)methyl]-4-chlorobenzene, 5.67 g (77.6 mmol) of azetidin-3-ol (2) and 18.4 mL (105.75 mmol) of DIEA in 250 mL of acetonitrile was rapidly stirred for 1.5 h at rt to 91° C., Reaction mixture was concentrated to remove solvents and residue was purified by silica gel chromatography with hexanes/ethyl acetate/ammonia (2M in MeOH)=100/30/0.5 to afford the title compound; 1H-NMR(CDCl3) δ 2.03 (br s, 1H), 2.81 (m, 2H), 3.55 (m, 2H), 4.34 (s, 1H), 4.50 (m, 1H), 7.29 (m, 4H), 7.34 (m, 4H).
